I received this update on 01st Oct 2014 from ACCA Student Accountant news alert which appeared in the Editors choice section.
“As a direct response to feedback from students, ACCA will be introducing four paper exam sessions, starting with a staged approach in September 2015. From 2016 you will be able to take your exams in March, June, September and December, meaning that you can choose the ACCA journey that suits you.”
I am pretty excited to know this and seems like we will get the details of the changes by ACCA soon.
